Capital One Senoir Software Engineer interview questions

Interviewed a couple of weeks back after doing the OA. Like others said you just needed to submit the first two questions to pass the OA. I also did part of the 4th. The actual interview was scheduled 2 weeks later, broken down into 4 parts system design, coding interview, case study, behavioral. 1) System design - Was my first time doing system desgin and was very unprepared. Could barely answer the questions. Chances were basically over after this point. The question was to design a banking app that could handle transactions etc. I recommend to know the HLD and then pick a specific technology and explain why you picked it, dont just guess. Go on leetcode discussion section and look up credit card to get started 2) Coding Interview - I was prepared for leetcode style interview, but instead it was a OOP oriented question that was split into 3 parts with each part building upon each other. The question was to design something (implementation to you) that could create user accounts and, store all their transaction, and do transfers between accounts, and return a sum of all transactions the certain accounts did. (these requirements were split into multiple parts). Tip: Makse sure you store all transactions. Was able to answer 2/3, ran out of time on the last one, but not too hard. go to exponent and look up "create-a-banking-system" 3) Case study - didnt really study much. Just some analysis of data and code like others said. Wasnt too bad, just think critically 4) Behavioral - standard questions Time you disagreed with coworker or manager, time priorites shifted, time you had to learn something new for a task good luck
